JERSEY Original application filed March 17, 1919,'Seria 1 No. 283,018. Divided and 1927. Serial This invention relates to mechanism :for

feeding strips, andithe embodiment of the invention herein illustrated'and described is designed particularly to feed to nail making machines'the metal strips from which they nails are formed. The present application is a division of my copending application, Serial283,018, filed March '17, 1919, upon tvhlch Letters Patent of the United :StatesNo. 1,651,452, were granted December 6, 1927, in

which I have shownand claimed a new and strip in the-carrier for automatically supplyingstrips to the carrier. Mechanism is also disclosed therein for transferring the 7 strips of material from a series of magazines,

' in each of which a strip is originallyplaced, to the carrier Which presents the strips tothe mechanism operating upon them and ,the operation of the transferring mechanism 'is'subject to a controlling mechanism which is governed bya feeler directly responsive'to the presence or absence of a strip inthe carrier, wherehya continuous supply of stripsis assured for presentation to the operating mechanism with assurance against supplying them faster than needed'and so jamming and possibly injuring the various mechanisms.- When'the cont-rolling mechanism has effected an actuationof the'supplying means, it is rendered inoperative to cause further actua tion until reset by the introduction of a new.

strip into the carrier. The introduction of more than one. strip atva time into the carrier is thus avoided, as Well as useless repeated actuation of the supplying means, .in case of anempty. magazine. One of the objects of the present,invention is to provide improved:

mechanism of the same general character as presenting means in MECHANISM non FEEDING STRIPS is pplication filed March 9, No. 174,078.

that formingthe subject inatt'er of said Let ters Patent, No, 1,396,191;

In aceordancewvi-th one feature-of the. pres-- ent invention themechanism for controlling the means for-supplying strips toa rotary carrier, with is mounted upon a support; with respect to which the carrier rotates. Regarded from;

another aspectthis' feature comprises an--instrumentality hich is movable :With thesupplying means for rendering inoperative ;the.

means for actuating the supplying-means.

lEecause ofthe fact that the means for renderlng the actuating means inoperative is moved, the actuat ng means tselfmay hemade sub.

stantially stationary. An advantage result-- ing from this feature, regarded from-1 either aspect, resides; in the factthat most of the in; strumentalities which, go to makeup the meansforcontrolling-the, supply of strips to r therotary carrier; do not-need to be designed;

which the machine isprovided,

to be ,carriedupon Y tl1e;;r0tary,carrier and,

therefore, can he made, morerugged, permitting less expensive workmanship, Furthermore, those instrumentalities of; the, controlling means which do not need to be'mountedi upon the carriercan be positioned out of: the

Wa-yof the lime dust arising froinjthe usual lime coating upon the strips. This; lime dust has a tendency to accumulate on oiled surfaces and impalr their lubrication; and anim-i portant advantage ofthis featureof the-yin 1 Another ohjectof, the, invention is to provide -means for positioning the'end of the strip which projectsrearwardly of' the' magazine from vwhich thestrip is supplied to'the such manner relatively: to the device for transferringthe stripto vention is that it avoids this .d-iiiieulty.

the presenting meansas to insure the proper andefiicientfop'eration'of the transferring device on the strip. In the illustrated construction, -the supplying means comprises a pluralityof magazines each adapted to contain" a single strip, and the magazines are moved successively into alinement with the present ing'means and'the pathof movement of-thc transferring device In accordance with :thisobject, a feature of the invention con-sists in theprovisiors ofmeans preferably organi ed to guide the rear ends of the strips and to dispose the strips in a vertical plane thus preventing them from being bowed downwardly at their ends by the force of gravity.

Another important feature of the invention resides in the provision of means for controlling the nozzle through which the strips are conducted to the cutters or other operating instrumentalities of the machine which'will insure the accurate presentation of the strips to the cutters and will, nevertheless, permit the ready discharge of the butt Nan ones of the-"strips fromthe machine. making machines commonly comprise agstationary anvil against which th cutters operate to sever the nail blanks fromthe strip, and, in the'preferred embodiment of the inventionthe controlling'means for the nozzle comprises a positioning member disposed to controlling means for the strip supplying Fig. 3 is a and its supporting frame;

contact with theedge of the strip forwardly of the end of'the nozzle and means spacedrearwardly from the end ofthe nozzle for maintaining the strip against the positioning member, the'surface ofthelstation'ary anvil beingthus left unobstructed at-one side there by permitting the butts of the strips to pass freely' therefrom.

The invention further provides an improved nozzle mechanism which -W1ll facih tate the accurate presentation of the strips 7 to the cutters.

Althoughthe invention will hereinafter described as embodied in mechanism for feeding strips to a nail making machine, it is recognized that in various of its aspects the invention is not limited to such use. Accordingly, the scope of the invention is intended to be limited only as required by the claims. Still other objects of-the invention will appear as the description proceeds and will be pointed out in the appended claims.

The illustrated machine comprises a frame 2 upon which is mounted a head 4: carrying the mechanism for operating on a nail strip whiclnasshown, includes cutters .6 and 8 moved downwardly by a cam shaft lO past. j the edgeof a stationary-anvil 125. As op 14 recesses in their ends adaptedto receive the: cone-shaped ends of a rod 31 passing through the hub of the frame 22.] The frame 22is slidingly adjustable on the rod 31 and may be maintained many desired position of adjustment thereon by a set' screw;32..-

The strip carrier 16 is disposed obliquely of the edge of the anvil 12 to the end that the strip may be caused to project further at one of itsedges from the aiwil' than at its otheredge so that the blanksevered from the strip, will taper from one end to the, other. Itis;

. of, course, necessary to change, the relation ofthe strip to the anvilv in order that the blanks severed from the strip subsequently to the 'first one shall alsobe taperedj This. may be effected in various ways but, in the illustrated construct on the'carrier 16 1S rotated through an angle of 180 between consecutive operations of the cutters 6 and 8 to present the strip in alternately reversed relations to the cutters-by a passing over a sprocket wheel 34 on the carrier 16 and driven. from a shaft 36 ournaled' in the frame 2 of the machine and carrying sprocket chain 33 an eccentric gear 38 meshing witha like gear,

on a shaft 40 driven by a cl1ain'42 from the cam shaft 10. A link 43 connected to the frame 22 is operated fromthe shaft 36 to. rock the carrier 16 about the fulcrumstuds 28.

to elevate the carrier and thereby to permit the carrier to be rotated without interference,

of the strip with the anvil l2. 1 The arrangement of the eccentrlc gears is such as to rotate the carrier at relatively slow speed when i the strip is lowered on the anvil 12 to facilitate the operation of the cutters 6 and 8 on the strip.- 7

The frame 26 may be adjusted laterallyof the head 4 so as to vary the degree of taper of the nail blanksevered from the strip. As shown, the frame is joined to the head 4 by links 44 and is provided at its rear end with a tongue slidable in a groove 45 in the up- Y per end of a supporting standard 46. The groove 45 is curved substantially concentri cally with the point of operation of the out ters 6 and 8 on the strip, andthe frame 26 may be ad usted, in said groove by a screw 47 (see F1g. 11).

The nail strips are fed through the strip carrier 16 by rolls48 journaled in the cast-- ing 17 and rotated intermittently to feed the strip by pawls 49, which are in turn actuated by a stud 50 with which they are moved into engagement by the rotation of the strip car rier. The stud 50 is carried by an arm 52 (Figs. 2 and 3) pivoted in the frame 22 and coacting with an adjustable stop in-the form of a set screw or the like 53 to determine variably the extent of the strip feeding move- The pawls 49 are to the strip carrier 16 from a turret comprising a plurality of magazines 62 each constructed to rece1ve a single strip. -The magazines 62 are disposed parallel to and concentrically ofthe a-Xisof the turret which is rotated step by step to aline the strips in the magazines successively with the carrier 16 by a Geneva movement designated generally by the numeral '63, Fig. 3, which is driven, through a sprocket chain 64,by a

sprocket wheel 65,'the hub of which is mounted loosely on a tubular extension 165 (Fig. 6) of the strip carrier 16 and is adapted to beiclutched thereto when it is desired to supply a. strip to the carrier. The sprocketchain drivesa shaft 66 and ll) arm and extended rearwardly of the and adapted to engage one of a uponcwhich the driving member of gthel Geneva .movement 68' is mounted and which is'extended rearwardly of the turret 60rto actuate mechanism for transferring he strips from the magazines 62 to the carrier 16. As shown, such mechanism comprises a cam 68 on the shaft 66 operable on aroll 70 carried by an arm 72 mounted for swinging movement on a stud 74, the arm 72 having a bent rod 7 6 extending therefrom and connectedat its free end by a link 77 to a transferring device 78 slidable on abar 79011 the frame 26. The transferring device 78 comprises a palm disposed laterally of the bar 79 imposition for engagement with the end of a strip in a magazine alined with the strip carrier 16. The cam 68'm0ves the transferring device rearwardly on the bar 79 seas to permit the rear end of a strip to pass in front of the palm 80 when the; magazine conta ning the strip ismoved into almement with the str p carrier, such dev1ce being moved forwardly to transfer the strip from the magazine to the strip carrier by yielding.meanswlnch, as shown, comprises a shrin 81. Itwill be understood from the foregoing that when. the sprocket wheel-65 is rotated throughonerevolution, the turret,

60 is 'moved forward far-enough to carrv one o-ftwo adjacent magazines 62,0ut of and another into alinement with the stripcarrier 16and the transferring device 78 is actuated to transfer the strip in the secon'd magazme to the carrier l6.-

Certain of the features of tl'iejmachine hereinbeforereferred to are fully described 1n the above-mentioned prior Letters Patent,

and a more detailed description of such parts 7 of the machine in this application is believed to be unnecessary to a full understanding-of the present invention. e V

In accordance with the invention}, the sup ply of fresh'strips to the, carrier 16 is efiected automatically soas to maintain a continuous supply of strips in the carrier, and the operation oft-the supplyin means isinitiated by W means on the-tubular strip carrier 16 con trolledby a strip in. the carrier and adapted to actuate controlling means for, the clutch connections between I the sprocket wheel 65 and the carrier 16, As shown, such connections comprise an-enlarged portion 82 (Fig,

7 on the hub ofthe sprocket Wheel 65 in Wlllitll lS provided a recess 84 to recelve" a pin 86 having a finger 88 projecting transversely from its'middle portion, the pin being fiattened at one side of said finger at .90. The, I

' flattened portion of the pin 86 is disposed so as to intersect thepath inwhich a lug92 on the sprocket wheel 34 moves. y The means for controlling theclutch connections between the carrier 16 and the i sprocket Wheel 65 comprises a dog94 and a shifter for the dog Which, as shown, includes a 96 upon which the dog is loosely- 7 surface of the dog 9 1 to receive the edge or the spring 103.

mounted and which isjournaled in an eic tension 98 of the bearing 20 ofthe frame 22.

The hub of the dog 94 is maintained normally against a shouldered surface 100 on a wing 102 forming part of the ex i io n. 98 by a spring 103 attached at one of its ends to the wing 102 and at its other end to a lug 10% pro jccting rearwardly from the hub of the dog 9s Mounted on one end of the shaft 96 is an arm 106 having a boss 108 at its lower endi shifter to each other in'either of awe relative The shifter further comprises a" positions. member 118 on the other end of the shaft 96 formed with divaricate arms 120 and 122 each having its end disposed ad acent to the' carrier As shown in 5, t 1e arm 120 is offset somewhat in advan'cieot the arm 122 for a reason that will presently appear; "The dog 9a1is formed with an arm 12%: underlying the hub of the sprocket wheel anddisposed to be engaged by therenlarged portion 82 of 'sald hub simultaneously \v t'hfthe engage,- ,mentjof the arm 106'by a second cam portion 126 on said wheel. r

The shifter for tire dog 94is-actuated by a feeler illustrated asafinger'128 fulcrumed at 130 on the carrier 16 and having one of its ends normally urged tdwards the path of movement of the stripsinthe carrier by a spring 131 and its other end 132 projected outwardly from the carrier.

The manner of operation'of the mechanism by which the supply of fresh strips to thecarrier is initiated and controlledwill now e described. issuming that the finger 128 is in engagement with a'strip in the carrier .16, the plunger 110 will be engaged in the notch 116 of the dog ,94E which is held against the shoulder ofgthe wing 102 by \Vhen the rear endof the strip in the carrier moves past the finger 128, the finger'is swung about its pivot 130 out-.

wardly and forwardly bythe spring 13 1 to a position such that upon continued rotation. of the carrier the end 1320f the finger impinges upon the end of the arm 12 0 and through the connection between the plunger 110 and the dog- Q i mdves the dog from ben'eaththe finger88. (So long asfthefinger'88 is upheld by thedog 9 1 the flattenedportion of the pin 86 is so disposed relatively to the lug 92 that the lugwill pass by said pin during-the rotations of the gear 3st without engaging the pin. Upon thewithdrawal of the dog 94 from'beneath the. finger 88, however,- the fpin 86 upon' the force of gravity acting onthe finger 88 is turned so as to dispose the flattened end of the pm across the path of movement of the lug 92, so that continued rotation of the gear wheel 34 will cause rotation of the gear wheel 65. If thegear wheel 65 were to be continuousoperation of the strip supplying-means is,

in the'operation of the illustrated construction, prevented by movement of the arm 106 outwardly by the cam 126 while the dog 94- is withhelc from movement by the action of the enlarged portion 82' of the wheel on the arm 12a. of the dog. Such movement of the arm 106 carries the arm 120 away from'the carrier 16 and out of the path of movement of the end 182- of the finger 128, the plunger 110 being at the same time moved from the notch 116 to the notch 11 1. \Vhile the plunger 110 engages notch 11 1 the arm 106, togetherwith the arm 120 which is rigidly connected thereto through shaft 96, is held in such relation ,to'the dog 9 1 thatwhen cam portion 126 passes away from arm 106- arm 120 is held out of the path of movement of he end 132 of finger 128, and this in spite of the fact thatdog 9 1 is held by spring 103 in the path of m'oven' 'ent of finger 88. -Thus looking at the parts from the direction in which they are viewed inFig. 6, and assuming-them to be'with dog 94: held by spring 103 in the position there shown, when the plunger 110 is moved from the position there shown to the position in which it engages notch l'l h'arins 106 and 120 move counter-clockwise to such an extent that the extremity of arm 120 is no longer'in the path of movement of the end 132 of finger 128. It will be understood that the dog 91: is returned into the path'of movement of'the finger 88' by the spring 103 immediately after, the finger 128' passes out of contact with the end of'the arm 12 0. Accordingly.

when the gear wheel" 65 has completed a single revolution, the finger 88 onthe pin 86 will be again engaged by dog 94, inasmuch as the arm 120-is no longerin position to be actuated by the finger 128, and will turn the pin to 'unclutchthe gear wheel 65 fromth-e gear wheel34t." With this constructiomonly designed to supply a single strip to the cary rotated, a number of strips would be rier is efiected whether a strip is actually supplied to the carrier or not,-and repeated useless operation of the supplying means will be avoided.

when a fre'sh'strip is introduced into the carrier, it, pushes back the inner end of the.

finger 128, thereby positioningthe end 132 of the finger inwardlyand rearwardly so as to wipe upon the upper surface of the arm" a: 'singleoperation of the supplying means the da so as to carry the plunger 110 from the no 114 hack intothe notch l16thus resetting the clutch controlling means. This completes the cycle of operations, the end 182 of the finger 128 being then maintained out of operative relation. to v the arm 120 against the tension of the spring 131 by the strip until th rear end of the strip passes from engagement with the finger 128 after which the finger will again actuate the arm 120 to initiate the supply of another strip to the carrier. Theabove-mentioned oll'set between the arms 120 and 122 enables these arms to be engaged by the end182 in its forward and rearward positionsrespectively.

In order effectively to control the strip in its passage'throughthe' carried and to position it accurately with relation to the feed rolls 48, a strip guide 184 is secured to the main castingl'? of the carrier rearwardly of g the feed rolls, the term rearward being employe'd to denote that direction which is opposite to the direction of feed of the strip. Preferably and, as shown (see l0)"such guide comprises a sheet metal plate formed with a rearwardlv extending ear 186 secured to thecasting 17 by a set screw or the like 137 (Fig. 8) and recessed at its under side to receive the strip. Wings 138and 140-are provided on the plate for ment with the edges of the strip in the carrier, said wings being preferably constituted by integral portions of the plate bentlaterally'to form the recess for the strip. A'third flexible wing"142 is carried the plate for contact with a side of the strip. The wings 138, 140, and l42 exten'd'frorn the plate toward the'feed rolls 48 and their ends engage the stripadjacent to the point of operation of'the feed rolls on the strip.-

It has been'fo'un'd'in the use otinachines of the'type of the illustrated machine that the rear e'n'ds'ot the strips when allowed to hang free from the magazines 'arefr'equently not properly positioned relatively to the palm 80016 the transferring device 78 when the magazines containing them are moved into alinem'entwith the strip carrier. I For example, the endof the strip inthe alined magazine is sometimes bowed downwardly by the force of gravity to an extent such that the pal'r'nSO does not engage the extremity of the strip but is carried against its side so that the palm is caused to bend the strip at the end of the magazine instead of pushing it forwardly into the strip carrier. Inorder to insure the proper positioning of theend'ot the strip for op'era'tion'thereonby the palm 80,1 have provided the following" mechanism (see'fFig. 11). A bracket'144 onth'e frame yielding engage 2'6 is formedwithanupper arm 146 and a lower arm 148.. The arm'148 has secured thereto preferably by being formed integrallytherewith a-t'racflg 150-havin'g one of its ends disposed substantially in the horizontal plane of the lowermost gem of the path of move merit of the magazines and extending, lateral- "lyfoft the path ofmovement'ofthe ends of the stripsin the magazines by a distance such as topreclude the possibility of a strip passing beneath the track. The other end of the track 150 is curved upwardly and has spaced above ita correspondingly curved nember152 car ried by the upper arm 146.. Secured to the members 150 and 152 by blocks 153 and 154 clamped upon them by set screws 15 5' and 156 are flat curved spring members'158 andi160 respectively. The members15'0 and 153' and their flexible extensions 158 and 160 guide the rear ends of the strips andsupport them during part of their movement to thetransferring device 78. The extensions 158 and 160 extend upwardly across the path of movenent of'the transferring device 78 and inasmuch as they are spaced from each other by a distance substantially equal to the thickness of a strip, they maintain the strips in a vertical plane. Being flexible, the members 158 and 160 yield readily to permit the movements of the transferringmember. 'Itwill be understood that a strip disposed in a hori- Zontal plane in one of the magazines 62 may bow downwardly considerably at its end sinceit will flex readily on its lower side.

lVh en, however, the "strip is'disposed in the magazine in a vertical plane with an edge of the strip on its lower side, it will not fiexto any appreciable extent. I

When the turret recharged, the ends of the strips in the magazines at the upper part of the turret are liable to be bent down far enough to be engaged by the palm 80 of the transferring device. To prevent this, I provide'means for supporting the ends ot'such strips which, the illustrated construction,

is exemplified by abent rod '162 extending upwardly from the arm 146 and being formed with the downwardly and upwardly inclined portions 16 3- 'a'nd v164 forming a saddle in whichthe stripsrest. 1 v

The strip car' rier 16 is provided with a nozzle 166 received-in a passage 167 '(Fig. 4) of the main casting 17" otthe carrier and held in place in the casting 'by suit-able means wh ch, as shown, includes a latch 267 (Fig. 15) having a reduced end fitting into an opening in the nozzle and normally maintained in locking engagement with the nozzleby a spring 168 receivedin a bore of the latch 267 and operating against "a pin 268 passing through an opening in the latch large enough tOPGIIhlt it to be moved'ag'ainst'the resistance of the spring 168 to release thenozzle. A pin or the like"(no t shown) on the nozzle 166 is received in a slot 269 of themain casting 17 of the strip carrier '(see'Fig-2) and thus limits the lateralmovements of the nozzle about the'latch 267. An inverted U-shaped leaf spring 169 secured to thehead of the machine by a block 2T0iengages the nozzle 166 at point remote from the delivery end of the nozzle and insures' the proper positioning of thestrip for operation thereon by the cutters 6 and 8 by urging the edges of the strip against the positioning member 271 (see Fig. 2) as the strip is turned by thecarrier 16. It is impossible to convert the strips 'into nails in their entirety, inasmuch as they cannot be controlled by the nozzle so as to present them to the cutters when they are nearly used up. In the operation of nail making machines as heretofore constructed, considerable diiliculty has been experienced in discharging the butt ends of: the strips from the machine, so that they frequently accumulated on the fixed anvil where they interfered seriously with the operation of the nozzle'and the cutters. Such ditiiculty is, however, avoided by the present'construction, since thereby the upper surface of the stationary anvil 12 is left unobstructed at one side, as'will clearly appear from Fig. 2, from which it will be seen that the butts may pass readily from the left side'of'the anvil 12.

he invention further aims to improve the construction. of the nozzleso as better to present the strips to the cutters. To this end, there-are fulcrumed tothe nozzle 166 by bolts 170 and 171 respectively, members 172 and 17 4 having their ends 17 6 and 17 8. extending beyond the delivery end of the nozzle 166 and bein grooved to receive the marginal portions of the strip. Said members are U- shaped in cross-section so asto embrace the edges of the nozzle 166 and their sides are bent inwardly intermediate between their main body portions and their grooved end portions over the shoulders formed at each side of the delivery end of the nozzle by the reduced extension 367 thereof? Leaf springs 180 and 182 secured to the sides ofthe nozzle by the bolts.170 and171-extend outwardly from the end of the nozzle;tosubstantially the same extent as themembers1-72 and 174 andare adapted for engagement with the sidesof the strip. The grooved ends '17 6 and 1T8 of the members 1'421and' 174 are maintained against the edges of the strip in the nozzle by plates 184 and 186 slidably adjustable on the nozzle andsecured in any desired position of adjustment thereon by bolts 188 and 190 passing through; elongated slots in in the plates. As shown, the members 172 and 174 are bentoutwardly, at their rear ends 192 and 194 away from the sides ef-the nozzle 166 thus presenting inner surfaces diverging from the sides of the nozzle against whichthe plates 184 and 186 operate. The plate 186 has formed thereon an extension 1961bowed outwardly at 198 for engagement with the end 194 of the member 174, and the plate 184has an extension 200 bowed out wardly at 202 for engagement with the end 192 of the member 172. The end of the extension 196 contacts with the side of the nozzle 166' and thus maintains the grooved end 17 8 of the member 174 positively against outward movement. The extension 200, however,is spaced at its end from the side of the nozzle 166 in order to permit the grooved end 176 of said member to yield outwardly when required to accommodate itself to the strip.

To facilitate the flexure of the extension 200, y

it is continued into the body of the plate184 by the formation of a slot 204 in the plate. The plate 184 is formed with a flange 206 fitted into a slot 208 in the nozzle 166 in order to assure a firm support for the plate. The maintenance of the member 17 4 in fixed position enables the strips to be presented inva riably in the same relation to the cutters 6 and 8, whereas if both of said members were yfeldingly mounted, both might'be simultaneously moved in the same direction from their normal positions thus causing'the strip to be improperly positioned relatively to the cutters. The normal positions of the grooved I ends 176 and 178 of the members 17 2 and 174 may be suited to the width of the strip being operated upon by adjusting the plates 184 and 186.
